My 2000 Toyota Camry's hood lift struts have to replace. I bought two new ones without end fittings. I am supposed to reuse the old end fittings. However, they are ball studs inserted into ball sockets without retaining clips or things like that. I don't know how to remove the old hood lift struts without cutting off the ball studs. Any suggestions on what to do and what tools to use will be greatly appreciated.
